demagnatise

Dear readers,

We sometimes have to demagnatise rolls off hard steel types. This is usually done with a AC-yoke. On some rolls this removes all magnetism effectively, but on other rolls a fine pattern of considerably strong magnatism is introduced in the roll surface. Could anybody give (practical) advise on improved procedures to demagnitising these rolls?

Thanx, Elmar van den Elzen
